I needed a radio button choice of Vimeo Video or Image for a slider.
I did this:
<?php if(get_field('hero_slider_slide','option')): ?>
<ul class="slides">
<?php while(has_sub_field('hero_slider_slide','option')): ?>
<?php if (get_sub_field('hero_slider_video_or_image', 'option') == 'Vimeo Video') { ?>
<li>
<?php echo '<iframe id="player_1" src="http://player.vimeo.com/video/'. get_sub_field('hero_slider_vimeo_video','option') .'?api=1&player_id=player_1" width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>' ?>
</li>
<?php } else if (get_sub_field('hero_slider_video_or_image', 'option') == 'Image') { ?>
<li>
<img alt="<?php echo $alt; ?>" src="<?php echo $image[0]; ?>" />
<div class="grid-container">
<div class="grid-100 tablet-grid-100 hero-caption">
<p class="tagline"><?php the_sub_field('hero_slider_slide_caption', 'option'); ?></p>
</div>
</div>
</li>
<?php } ?>
<?php endwhile; ?>
</ul>
<?php endif; ?>
